NON-REFILLABLE BOTTLE.

Application filed February 7, 191 1.

Specification of Letters Patent.

Patented July 2, 1912.

Serial No. 607,151.

To all whom it may concern:

Be it known that I, GEORGE V. DOHERTY, a citizen of the United States, residing at Somerville, in the county of Middlesex and State of Massachusetts, have invented new and useful Improvements in Non-Refillable Bottles, of which the following is a'specification.

This invention relates to improvements in non-refillable bottles.

The object of the invention is to provide a device which can be inserted in the neck of a bottle and which, when so inserted, will prevent liquid from being introduced into the bottle, but will not prevent the flow of liquid outwardly from the interior of said bottle.

The invention consists in the combination and arrangement of parts set forth in the following specification and particularly pointed out in the claims thereof.

Referring to the drawings: Figure 1 is a central vertical section, partly in elevation and broken away, of a bottle with my improved stopper attached thereto, the bottle being shown in an upright position. Fig. 2 is a sectional elevation taken on line 22 of Fig. 1, showing the bottle inclined at an angle and broken away. Fig. 3 is a sectional plan taken on line 33 of Fig. 1. Fig. i is a perspective view of the stopper.

Like numerals refer to like parts throughout the several views of the drawings.

In the drawings, 5 is a bottle having a neck 6 provided with a straight bore terminating at its lower end in a shoulder 7. In the interior of the neck 6 of the bottle 5 is fastened a stopper 8 which may be secured to the interior of the neck of said bottle in any suitable manner, such, for instance, as by cementing the body portion 9 of the stopper 8 to said neck.

The stopper 8 consists, as a whole, of a body portion 9, a head 10 and a stem 11, said stem being smaller in diameter than said head and said body portion, there being an annular shoulder 12 formed in said stopper surrounding said stem. The stopper 8 is hollow, being provided with an interior chamber 13 and'having a hole 14: opening through the bottom thereof. The hole lt in this instance is formed in a valve seat 15 inserted in the chamber 13 and preferably provided with a flange 28 which rests upon the body portion 9 of the stopper 8.

A conical valve 16, preferably hollow, is

provided with an annular flange 17 at the base thereof, which annular flange rests upon the seat 15, thus closing the hole 14 when the bottle is in an upright position as in Fig. 1. The valve is held'firmly upon its seat by a ball 18 which is located inside the chamber 13 of the stopper and is adapted to engage the base of the valve and preferably to project into the interior of the hollow cone and press the valve against said seat 15 when the bottle is in an upright position. A stop 19 projecting into the chamber 13 from the wall of the body portion 9 of the stopper limits the distance to which the ball can move away fromthe seat 15 when the bottle is in an inverted or inclined position as illustrated in Fig. 2.

Two ports 20 and 21 leading outwardly from the chamber 13 connect said chamber to the annular shoulder 12. Two other ports 22 and 23 leading from the lower part of the chamber 13 also connect said chamber to the annular shoulder 12 and are connected to each other by an annular groove 24 which extends around the periphery of the body portion 9 of the stopper.

The head 10 is provided with grooves or slots 25, 26 which extend longitudinally of the stopper entirely across said head, thus opening from the shoulder 12 into the space in the bottle neck above said head. A cork 27 is inserted in the neck of the bottle above the stopper 8.

The operation of the device hereinbefore specifically described is as follows: Assuming the bottle to be filled with liquid, the cork 27 is removed and the bottle decanted from the position illustrated in Fig. 1 to that illustrated in Fig. 2. The ball at the same time rolls away from the seat 15 and the valve also moves from said seat and tips into the inclined position illustrated in Fig. 2. The liquid now passes out through the hole 145 into the interior chamber 13 and thence through the ports 20 and 21 and along the groove 26 and outwardly from the outlet orifice in the neck 6. WVhile the bottle is being thus decanted, the air which rushes inwardly passes through the port 23 or 22, as the case may be, into the interior of the bottle.

It will be seen that after the bottle is emptied, or partly empty, if it is attempted to insert liquid in the bottle, the slightest amount of liquid flowing inwardly into the bottle will enter the interior of the hollow valve relatively to said valve seat.

It will be seen that when the parts are.

cone 16 and drive it back onto its ,seat 15,

in the position illustrated in Fig. 2 the stop 19 prevents the ball 18 from passing out of the body portion 9 of the stopper and into the interior of the stem 11 and thus limits the distance to which the ball can move longitudinally of the chamber away from the seat 15 and also holds said ball against the side wall of the body portion 9, so that the same will not close up the interior of the stem and prevent the liquid from discharging from the bottle.

In order to assist the free flow of the liquid from the bottle when in the position illustrated in Fig. 2, the same is preferably pro vided with a tube 29 which is fastened to the valve seat 15 in alinement with a port or hole 30 extending through said valve seat. This hole or port 30 is located within the periphery of the flange 17 when said flange is in contact with said seat, so that when the parts are in the posit-ion illustrated in Fig. 1, the flange 17 closes the port 30 and pre vents any liquid from entering the bottle through this port or passageway, but when the bottle is decanted to the position illustrated in Fig. 2, the flange 17 being removed from the seat 15, then the air can enter in the direction indicated by the arrows through the port 30 and through the tube 29 into that part of the bottle which has no liquid therein, for instance, that part of the bottle which is near the bottom, and preferably the tube 29 extends nearly to the bottom of the bottle 5. Thus the air constantly enters the bottle and causes a pres sure upon the liquid therein to assist in its outflow.

Having thus described my invention, what I claim and desire by Letters Patent to secure is:

1. In combination, a bottle providedwith a chamber and an outlet orifice, a bottle stopper located between the interior of said chamber and said outlet orifice, said stopper diameter between said head and body portion, and an annular shoulder extending laterally inward from the side of said bottle and joining said stem and body portion, a valve seat between said body portion of said stopper and the interior of the chamber of said bottle, a hollow tapered valve provided with an annular flange at its larger end, the tapered portion of said valve being surrounded by said valve seat, a stop located between said annular flange and said annular shoulder and at one side of said body portion, and a ball located between said annular shoulder and said valve, adapted to engage said stop when said bottle is inverted, and to be thrown thereby against the opposite side of said body portion from said stop.

2. In combination, abottle provided with a chamber and an outlet orifice, a bottle stopper located between the interior of said chamber and said outlet orifice, said stopper consisting of a head, a body portion adapted to fit snugly said bottle, a stem of smaller diameter between said head and body portion, and an annular shoulder extending laterally inward from'the side of said bottle and joining said stem and body portion, a valve seat between said body portion of said stopper and the interior of the chamber of said bottle, a tapered valve provided with an annular flange at its larger end, adapted to engage said valve seat, a stop projecting laterally inward from one side of said body portion and located between said annular flange and said annular shoulder, adjacent to said annular shoulder, and a ball located between said annular shoulder and said valve, adapted to engage said stop when said bottle is tipped, and to be thrown thereby toward the opposite side of said body portion from said stop.

In testimony whereof I have hereunto set .my hand in presence of two subscribing witnesses.

GEORGE V. DOI-IERTY.
